"Modern UI (Metro) Charts for Windows 8, WPF, Silverlight" for .net 4.0
提问by masterchris_99
I'm searching for a good chart-control and found "Modern UI (Metro) Charts for Windows 8, WPF, Silverlight" This control looks really good but I need this for Visual Studio 2010 and 4.0. The original source is written in Visual Studio 2012 und 4.5 so I tried to create a new project with the class files. Everything works well. I can compile the classes and debug thru. But the result is an empty window. I don't know where the mistake is. The files are unchanged thats why I post some pictures:

The new Metro Charts are really good! Like you've mentioned, they are targetting Windows 8 and .net 4.5, but you can get them to run on Windows 7 with .net 4.0 in VS 2010 as well. Take a look at http://thusithamabotuwana.wordpress.com/2014/02/02/charting-with-wpf/if you need a quick tutorial on how to get started.
新的地铁图真的很棒！就像您提到的那样，它们的目标是 Windows 8 和 .net 4.5，但您也可以让它们在 VS 2010 中使用 .net 4.0 的 Windows 7 上运行。如果您需要有关如何入门的快速教程，请查看http://thusithamabotuwana.wordpress.com/2014/02/02/charting-with-wpf/。

I had to do two things to get it to work with VS2010. The first was that the databinding wasn't being brought along when setting the DataContext for ChartBase. That resulted in no data to plot. To fix that I changed ChartBase.OnSeriesSourceChanged to use LoadDataTemplate that loads the content then loops through and sets all the databindings:
我必须做两件事才能让它与 VS2010 一起工作。第一个是在为 ChartBase 设置 DataContext 时没有带来数据绑定。这导致没有要绘制的数据。为了解决这个问题，我将 ChartBase.OnSeriesSourceChanged 更改为使用 LoadDataTemplate 加载内容然后循环并设置所有数据绑定：
private void OnSeriesSourceChanged(IEnumerable oldValue, IEnumerable newValue)
{
this.Series.Clear();
if (newValue != null)
{
foreach (object item in newValue)
{
if (SeriesTemplate != null)
{
ChartSeries series = LoadDataTemplate<ChartSeries>(SeriesTemplate, item);
if (series != null)
{
// set data context
series.DataContext = item;
this.Series.Add(series);
}
}
}
}
UpdateGroupedSeries();
}
private static T LoadDataTemplate<T>(DataTemplate template, object dataContext)
where T : FrameworkElement
{
DependencyObject element = template.LoadContent();
T view = element as T;
view.DataContext = dataContext;
var enumerator = element.GetLocalValueEnumerator();
while (enumerator.MoveNext())
{
var bind = enumerator.Current;
if (bind.Value is BindingExpression)
{
view.SetBinding(bind.Property, ((BindingExpression)bind.Value).ParentBinding);
}
}
return view;
}
Second I had to change the project to including the correct Generic.xaml file. Be sure to use the one under De.TorstenMandelkow.MetroChart.WPF/Themes. It needs to include the BaseChartStyle.
其次，我必须将项目更改为包含正确的 Generic.xaml 文件。请务必使用 De.TorstenMandelkow.MetroChart.WPF/Themes 下的那个。它需要包含 BaseChartStyle。
